H. H. BAKER, OF NEW MARKET, NEW JERSEY.

ARRANGEMENT OF THE FEED-ROLLER IN WOOD-PLANING MACHINES.

Specification of Letters Patent No. 22,926, dated February 15, 1859.

To all whom it may concern:

Be it known that I, H. H. BAKER, of New Market, in the county of Middlesex and State of New Jersey, have invented a new and Improved l/Vood-Planing Machine; and I do hereby declare that the following is a full, clear, and exact description of the same,

reference being had to the annexed drawings, making a part of this specification, in which- Figure 1, is a front elevation of myinvention. Fig. 2, is a transverse vertical section of ditto, taken in the line w, m, Fig. 3. Fig. 3, is a plan or top view of ditto, with the cutter wheel or disk horizontally bisected.

Similar letters of reference indicate corresponding parts in the several figures.

This invention consists in placing the feeding device under the complete control of the attendant or operator, so that the said device may be thrown in and out of gear with the work without stopping the working parts of the machine.

To enable those skilled in the art to fully understand and construct my invention, 1 will proceed to describe it.

A, represents a framing which may be of metal or wood and constructed in any proper way to support properly the working parts of the machine. On the upper part of the frame A, a metal head B, is firmly secured, and in this head a horizontal shaft or arbor C, is placed, said arbor having a pulley D, placed on it, at about its center, pulleys E, E, on its outer end and a wheel or disk F, on its inner or opposite end.

The wheel or disk F, is of metal, may be hollow, and has a solid face a, in which two annular concentric grooves or recesses b, c, are made, the groove or recess 6, being at the edge of the wheel or disk, and the groove or recess 0, encompassing the center... The grooves or recesses b, 0, form two prominences cl, 6, on the face of the wheel or disk, as shown clearly in Figs. 1 and 3.

In the periphery of the wheel or disk F, there are two cutters G, H. These cutters are fitted in recesses in the periphery of the wheel or disk and their cutting edges project, corresponding of course to the thickness of shaving cut by them. The cutter G is a planer or finisher and has a chisel edge, as usual, but the cutter H, is a gouge, and is a tube the cutting edge being perfectly circular, see Figs. 1 and 2. This gouge H is fitted within and secured to the wheel or disk by a metal strap f, attached. to the wheel or disk, and it may be adjusted and turned on the wheel or disk as occasion may require by loosening the strap 7, by adjusting a nut g, within the wheel or disk, see Fig. 3.

To the front side of the head B, there are two horizontal and parallel bars h, which may be cast with the head. On these bars h, a horizontal metal bed plate I, is permanently secured. On this bed plate a gage J, is placed, said gage extending the whole length of the bed plate, allowed to slide transversely thereon, and secured at any desired point by a set screw 2', which passes through a transverse slot 7' in the bed Z; of the gage and into the bed-plate I. The front and back ends of the bed is of the gage project down over the ends of the bed plate, and have set screws Z passing through them and bearing against keys m, which are fitted in the ends of the bed plate, see Figs. 1 and 3. By adjusting the screws Z, Z, the gage may be fitted to the bed plate as snugly as desired or as occasion may require.

K, is a shaft, one end of which has a toothed wheel a, placed on it, said wheel being inclosed within a cylindrical box or case 0, attached to the framing A, the inner side of said box or case having the bearing 3), of said shaft attached, as shown clearly in Figs. 2 and 3. The opposite end of this shaft is also fitted within a box L, and has a bevel pinion 9, attached to it, said pinion gearing with a horizontal bevel wheel 1", which is placed on the lower end of a shaft M, which is stepped at the bottom of the box L, and has a toothed feed roller N, secured on it, the back part of said roller being covered by a metal shield 8, said shield being attached to box L. The upper end of the shaft M, has its bearing in a plate t, which is attached to the upper end of the -s shield s, as shown clearly in Fig. 2.

The box L is attached to a sliding bar 0, which is fitted in guides 10, u, at the under side of the bed 'plate I, and a spring P, which is attached to the under side of the bed plate I, bears against the sliding bar 0, and has a tendency to keep the feed roller N toward the gage J. To the under side of the bed plate I, a lever Q is attached, the inner end of said lever being fitted in the sliding bar 0, and the opposite end passing through a loop 41, within which there is a catch or projection to retain, when necessary, the lever and consequently the sliding bar 0, and its connections against the action of the spring P.

Into the toothed wheel a a pinion a", gears and this pinion is fitted within a box I), attached to box-0; the pinion (4*, is considerably wider than the wheel, the object of which will be presently referred to. On the outer end of the axle 0 of the pinion (0, a pulley d is secured. To the lower part of the framing A, three pulleys 6*, f 9*, are attached. 7

The operation of the machine is as follows: Motion is given the respective shafts C, K, from the pulleys 6*, f 9*, by proper belts in connection with the gearing n, 64*. The gage J, isadjusted on the bed plate I, so as to allow a sufficient space between the gage J, and the face of the wheel or disk F, to allow the work, shown in red, to pass be tween it and the cutters G, H, which are adjusted according to the desired thickness of the shaving to be out; The spring P, keeps the toothed roller N in contact with the work, and said roller feeds the work along between the gage J, and the face a, of the wheel or disk F, the prominences 01, e, being the bearing surfaces. The gouge H, roughs OK the work or stulf, and the planer G smooths the work, the gage J, having a slightly oblique position with the face of the wheel or disk F, so that the cutters will clear the work as they move upward at the outer part or side of said wheel. The planer Gr, having a chisel face or edge, may be readily kept in proper working order and is not so liable to be injured by use, as it works after the gouge H, the latter is the more difiicult tool to sharpen and keep in repair and as it acts first on the work it is more liable to be injured, and ordinary gouges require to be frequently ground. The feed roller N, may be thrown in and out of gear with the work at any time by adjusting the lever Q, and the roller N as well as the other working parts may be kept rotating without actuating or feeding the work along, the pinion 64* being sufficiently wide to admit of a requisite length of movement of wheel a, without disconnecting the two wheels or throwing them out of gear, it being seen that the feed roller N, box L, shaft K, and slide Q, are all connected. The work, therefore, may when necessary be instantly stopped without stopping the running or working parts of the machine. The covering of the gearing by boxes 0, 6*, L, and protecting the roller N, by the shield s, prevents the shaving coming in contact with and injuring said parts.

I do not claim the cutter wheel or disk F, in itself considered, nor do I claim the adjustable gage J, for they have been previously used, but

Having thus described my invention, what I do claim as new and desire to secure by Letters Patent, is

Arranging the feed roller N, substantially as shown, to wit, connecting it with a vibrating shaft K, box L, slide 0, spring P, and with necessary gearing so that said roller may be kept to the work or moved out free from it without stopping the working or running parts of the machine.
